Apogee Duetta II Signature Crossover Caps Recommendations

I too will be getting my Apogee's Duetta 2 Sig's rebuilt as well, I have found from friends that the sprague caps are good caps and have been around for many years, but the Auracaps are better and are much smoother in the mid-range, I don't know much about the Multicap PPMFX
but the Spragues and the Multicap's are priced about the same on Parts Express, But the Auracaps are much more, Now lets talk about sound, well The Apogee Ribbons will NEED POWER so I have two Hafler Transnova's on my ribbons in a mono block config, because I don't want to worry about my amps taking a dive when that impedance dips, I also have Acoustats 2+2 , 6600, and spectra's and I have bought many amps to there knees, Because of the dip, so you will have to factor in the burn in time for your caps. Now if you are ok with building your own stand alone crossover boxs with the caps that you are thinking about using you can't go wrong with that approach, just stay on the same value as the original caps are rated for. that would give you the joy of changing out you caps to what type of music you are listening to at the moment, you have to keep in mind that we have a pair of speakers that are many years old and what happens if the suppler of the ribbons stops making them, That is ALWAYS on the back of my mind like my Acoustats which all of the internal transformers and not labeled with part numbers, I hope that you are not paying a Hefty price for this refresh. you can reach out to me in a Email- Mosleygerald11@yahoo.com and I can provide more information you may need.

Hey that is great!! so it seems like you know what direction you want to go in with your Duettas, I have read great things about Mr Graz and the
improvements to the Duettas. Yeah UPS damages eveything they touch
i would not send such a great speaker through them to be shipped, plus they don’t like to pay insurance claims, Like the old saying go’s " WHEN YOU DEFINITELY HAVE TO GET IT THEIR "DAMAGED" UPS CAN DO IT!!! . I have been trying to find the Swiss Symo LS4X translucent ribbon, bi-wire speaker Cables, but has not had luck and I have heard about them being fussy with other cables, BAT audio is very nice gear and it must have sweet Synergy with the Duettas! I live in the San Francisco so
and there are a lot of audio gathering’s out here (b4 COVID) and sometimes I hear of guys getting rid amps, But it is great to hear you have a history with these beautiful speakers. the pair that I have was at a flea-market and had came from a storage locker sale, and the guy that had them at his stall said they are room dividers!! and people kept walking by them saying how nice of a room divider they were. I don’t know much more about them, But if you can share some info you may have that would be great, How much are you going to invest in your rebuild? b4 you stop. I included my email if you what to send me some info, I want to rebuild the WHOLE SPEAKER. when I got them one of the bass panels had a rip in it and the tweeter on the right side would not play, so they need a full rebuild for shure,I have heard of the guys in Nevada and may send them another email, they did not respond to the first one I sent, I need to know who they use for a shipper and then what are there procedures for sending the set to them, I will build wooden shipping boxes for them. take care my friend :)

Hey thank you for the info, I will build the boxes myself and will design them with a flex factor in mind, I used to build Giant Radiator boxes for shipping to truck manufactures Like MACK,and will be under a price point of $ 600.00.I have looked at Mr Graz site and Emailed him, I have yet to talk with Mr Rich Murray @ True Sound, when I did reach out to him on his web site and did not get a response that drew up RED FLAGS! with me, Plus when I search for a address on Google Maps, all I saw was mountains with white caps on top 2nd RED FLAG!! I don’t know about you but I have heard of peoples equipment and money disappearing. so if I have to send my product further away to a REAL address that would be fine with me,it would be nice if Mr Graz would teach some speaker rebuilder in California since we have so many parts suppliers to build these speakers, it would make it very profitable for him.Foam suppliers have come a long way from the 80’S and the Chemicals used to make form don’t BREAK DOWN aka FOAM ROT as they use to,I have done some research on these speakers and I do have a price point of what I will be willing to spend for a rebuild and If they are talking CRAZY MONEY to do this I may just set them out in the trash and stick with my Acoustats that I can get panels for, very easily and at a VERY REASONABLE PRICE. I’m not the one to buy SNAKE OIL SPEAKER CABLES AT 6K a pop or cable supports at $ 600.00 a piece. a fool and his money will soon part! . Take care
